NORTH Korean tyrant Kim Jong-un is grooming his young daughter for the top job after getting morbidly fat again, South Korean spies say.

It’s believed Kim, 40, is suffering from high-blood pressure and diabetes, weighing a whopping 140kg – or 22st – despite standing at 170cm.

Now he is said to be training his daughter up to take the reins as Supreme Leader – even though she is said to be just 11 years old.

Kim, a boozy operator also known for his smoking, comes from a bloodline beleaguered by heart issues.

He took over from his father Kim Jong-il in 2011 when he died from a huge heart attack.

Prior to that, Kim Il-sung suffered a sudden heart attack in 1994.

Current-day Kim appeared to have lost a heap of weight around 2021, but South Korea’s chief spy agency believes he’s put it all back on.

The National Intelligence Service (NIS) revealed to South Korean politicians that he is sending the scales off the charts at 140kg and therefore is at high risk of heart disease.

The NIS says Kim’s daughter, Kim Ju-ae, could be next in line for the thrown.

The secretive North Korea hasn’t divulged her official age but the NIS believes she is about 11.

Although she is yet to be officially designated his successor, she has set tongues wagging since late 2022, attending numerous events alongside her infamous father.

According to local reports, NIS secretary Park Sun-won said: “Kim Ju-ae is hinted at as a strong successor and is undergoing successor training.”

He added: “How North Korea refers to Kim Ju-ae and what activities she appears in are very significant.

Intelligence Committee secretary Lee Seong-won said: “Kim Jong-un is extremely obese, weighing 140kg and in his 40s with a body mass index that greatly exceeds the normal level … putting him at high risk for heart disease.”

“We have determined that he has been showing symptoms of high blood pressure and diabetes since his early 30s.

“If he does not improve his current health, there is a possibility that he may develop cardiovascular disease, which is a family history, so we are closely monitoring him.”

Others speculated his heavy drinking and smoking were behind the weight gain.

Kim decided to keep his 40th 𝐛𝐢𝐫𝐭𝐡day celebrations low-key amid rumours of his health battle in January.

But the Supreme Leader has recently been snapped by state media out in public as North Korea deals with a flood crisis.

Record-breaking rain lashed the country, leaving thousands stranded and prompting Kim to declare an emergency.

Pictures showed the leader travelling through flooding in a car, with his puffy face peering out the window inspecting damage.
